The Global ETD Search service is a free service for researchers
to find electronic theses and dissertations. This service is
provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Mechanisms of Vts1-Mediated Repression in S. cerevisiaeOrlowicz, Agata 25 August 2011 (has links)
Vts1p is the Saccharomyces cerevisiae member of the Smaug family of post-transcriptional regulators, which is a group of sequence-specific RNA-binding proteins that regulate target mRNA expression. Vts1p is known to mediate deadenylation-dependent degradation of target transcripts through the recruitment of the Ccr4p/Pop2p/Not deadenylase complex. By conducting a functional analysis of Vts1p deletion mutants, I demonstrate that two regions within Vts1p are independently capable of downregulating the expression of an mRNA reporter. I provide both genetic and biochemical evidence that suggests residues 170-523 regulate reporter expression at the level of mRNA stability and function through a mechanism that requires the Ccr4p/Pop2p/Not deadenylase, whereas residues 1-237 repress reporter expression at the level of translation and function through a novel mechanism. In addition, I map a direct interaction between the eIF4E-binding protein, Eap1p, and the Vts1p SAM domain, which suggests a model in which residues 170-523 recruit Eap1p to mediate efficient target transcript degradation.
